The release is scheduled for Monday the 28th. Some time after, there
will also be a 0.7.x release, which has the fixes that went into 0.8.0
and 0.8.1 backported, to keep the 0.7 branch alive for a bit longer.

Do you anticipate that support for OpenSSL 1.1 will be provided in the
0.8.1 release? Lack of support is blocking my compilation with vibe on
Fedora 26.

Good point, I managed to forget about that. I'll at least include a
manual solution that works with a version constant VibeUseOpenSSL11 or
similar. Robert Schadek fortunately has a PR already open that just
needs to be adjusted a bit.
